1、
- pim6sd 自动将自身配置为在所有支持多播的接口interfaces（IFF_MULTICAST flag）上转发 forward，即设置了 IFF_MULTICAST 标志的接口（不包括excluding the "loopback interface" and interaces that do not have an IPv6 address）。
- 如果多播组地址在SSM范围内（ff20:：/12和ff30:：/12），则pim6sd将充当SSM路由守护进程，
- pim6sd必须在IPv6路由器上使用。请确保使用sysctl将net.inet6.ip6.forwarding变量设置为1(# sysctl -w net.ipv6.conf.all.forwarding=1)。pim6sd要求运行守护进程的节点具有IPv6全局地址。pim6sd does not work properly when interface is dynamically added or deleted (e.g. ifconfig gif0 create).
git clone https://github.com/troglobit/pim6sd.git
cd pim6sd/
./autogen.sh
./configure && make
sudo make install-strip
# sysctl -w net.ipv6.conf.all.forwarding=1
# pim6sd -f /etc/pim6sd.conf -n -d all
-d Specify debug level， Use -d all to enable all debug levels.
-n Do not become daemon, run in foreground.
debug level 0xffffffffffffffff:......
